• Recurrent stroke.
• Participants who cannot comprehend and obey verbal commands.
Intervention: Subjects who fulfilled inclusion criteria are randomly selected into 2 groups and each group has 20 subjects.
GROUP I: (The experimental group underwent Isokinetic strengthening and balance exercises) A 6 week program which includes 5 min warm-up on stationary bicycle at low resistance followed by 65seconds stretches for hamstrings and quadriceps group of muscles on effected side. Strength training with knee extensors on isokinetic machine. 3 Sets of 6 to 8 repetition of maximum efforts followed by cool down section of 5 min of cycling, followed by balance exercises they are as follows:
The Balance Exercises Include Static Balance Exercises:
I Sitting Balance
II Standing Balance
Dynamic Balance
GROUP II: (The control group underwent conventional training)
Conventional Physiotherapy Treatment: A 6 weeks program which includes Active exercises for all groups of muscles in lower limb on effected side, Pelvic bridging followed by Modified pelvic bridging, resistance exercises for all group of muscles in lower limb with one kg weight cuff and manual resistance, weight bearing exercise in quadripod position, kneeling, half kneeling, standing, standing with single limb support, manual perturbations with wider base of support in forward, backward, sideways and finally progressing manual perturbations to narrow base of support.
Outcome Scale: Isokinetic device to measure peak torque of knee extensors on paretic leg. Berg balance scale to measure balance.
Statistical Analysis: Paired T-test has been carried out to observe the treatment impact between the groups before and after the treatment.
Results: After a 6 week treatment period, the subjects in the Group I (strength training and balance exercise) compared with the subjects in the Group II (conventional physiotherapy) had shown a statistically significant improvement with the outcome measures at 0.05 level.
Conclusion: Isokinetic strength training and balance exercise was found much effective in improving strength of quadriceps lower limb and balance in subjects with stroke.

Aim
To find out the effect of peripheral muscle strength training on exercise capacity in subjects with chronic obstructive pulmonary disease (COPD).
Need of the Study
Review of literature has shown that the COPD patients have reduced exercise capacity due to deconditioning from disuse of peripheral muscle. It is required to know whether strength training with structured exercise protocol is effective in COPD. The structured exercise protocol is to be implemented to upgrade the strength in a systemic way and to correlate this with quality of life (QOL). Hence the need of the study is to find out the effect of structured strength training protocol on QOL in COPD patients.
Objectives of the Study
• To find out the relationship between peripheral muscle strength and VO2 peak. • To find out the relationship between peripheral muscle strength and 6 minute walk distance (6 MWD) • To find out the relationship between peripheral muscle strength and quality of life.
Setting
Tertiary setting hospital, SVIMS, Tirupati.
Subjects
30 subjects who met the inclusive criteria with age of 40- 65 years and who perceived the Borg scale dyspnoea grade <5 were selected for this study and were allocated into control and experimental groups.
Method
Functional capacity was measured by six minute walk distance (6MWD), VO2 peak was measured by bicycle ergo meter and quality of life (QOL) was measured by SF- 36(Telugu version) questionnaire. They were administered on first day and again after four weeks. The data was analyzed within the groups and between the groups and results were made.
Results
6MWD, VO2 peak and QOL were significantly increased in both groups after rehabilitation. Conclusion Due to the peripheral muscle strength training there is significant change in 6MWD, VO2 peak and QOL between control and experimental groups. This study shows that there is an improved exercise capacity in COPD due to peripheral muscle strength training.

The performance of very large scale integration (VLSI) circuits predominantly depends on routing of interconnected circuits. The major problems in the design of VLSI layouts are wire sizing, buffer sizing and buffer insertion. These are the techniques to improve power dissipation, area usage, noise and time delay. The interconnect delay can be optimized by choosing proper buffer locations along the routing path. A stochastic based Particle Swarm Optimization algorithm is used here to optimize buffer locations to find the shortest path and also simultaneously minimize the congestion. The performance is compared with Particle Swarm Optimization based VLSI routing. The results obtained shows the proposed approach has a good potential in VLSI routing and can be further extended in future.

We propose a method that provides information-theoretic security for client-server communications. An appropriate encoding scheme based on wiretap codes is used to show how a client -server architecture under active attacks can be modeled as a binary-erasure wiretap channel. The secrecy capacity of the equivalent wiretap channel is used as a metric to optimize the architecture and limit the impact of the attacks. We also provide a method to design attack-resistant client-server architectures that are resilient and secure using wiretap codes. Specifically, the objective is not only to ensure reliable communication between client and servers in the presence of disrupted nodes, but also to guarantee that a malicious attacker hacking the packet information at compromised nodes is unable to retrieve the content of the message being exchanged. In principle, standard encryption techniques could be implemented to ensure secure communication between client and servers; however, instead of using traditional cryptographic tools to encrypt information contained in the packet, the proposed approach exploits the fact that the attacker only gets parts of the packets sent by the client. we define wiretap model as a java web application security framework in order to solve web application vulnerabilities. Wiretap model extends web application’s behavior by adding security functionalities maintaining the API and the framework specification. The security functionalities include Integrity, Editable data validation, Confidentiality, Anti-CSRF token.Keywords

In the proposed work deals with the heat transfer analysis of Magneto hydrodynamic third grade fluid flow over a horizontal circular cylinder with Biot-number effect. Using the Non – Similarity transformations, the governing partial differential equations are converted into ordinary differential equations and these equations are solved numerically by using an implicit finite difference Keller - Box method. The influence of emerging non-dimensional parameters, namely the third grade fluid parameter, the material fluid parameters, Magneto hydrodynamic parameter, Biot number effect and the Prandtl number, on velocities and temperatures are evaluated in the boundary layer regime in detail. Increasing the third grade fluid parameter and material fluid parameters are found to increase the velocity and opposite behavior is observed on temperature profiles. Increasing the Magneto hydrodynamic parameter is found to decreases the velocity and increases the temperature. An increasing the Biot number whereas the velocity and temperature are enhances and increasing the Prandtl number, the velocity and temperature profiles are in depresses .The study is relevant to chemical materials processing applications.Keywords
